Inertion on right-click-drag on linux with wacom stylus

Post by durilka »

Hi.

Just downloaded the demo and really love it.
But there's one issue which makes it a bit complicated.
When I drag stylus with right button down the motion is captured but with inertion, i.e. when i right-click on the canvas and drag it down, the pointer and the canvas follow the motion but way slowlier than i did it and of course arrives later(add here event query and i can wait for the drag to end for minutes if i was inaccurate...). Another example is the bone-weight change(this is where it brings most difficulties) - so I have to change the weight with numeric input. Doing the same with a normal(ps/2) mouse works ok, but switching from stylus to mouse just to drag someting is uncomfortable.

The system is Gentoo Linux 2.6(mostly probable 2.6.16) on Amd64 with wacom volito(with latest drivers from linuxwacom project, i.e pressure sensitivity is working).

Thanks for a great product!

update. I just realized that this happens on normal click&drag, just not so problematic with freehand, for instance.

One thing I can imagine that yor Wacom tablet sends much more position events than your mouse. Since some of the Moho's tools are written in Lua language (a kind of interpreter language, so it is slow) maybe these events are overloading the event processing system of Moho.


Are you using the tablet as X core pointer? I remember that X11 handles the core pointer with a lower event rate than the secondary input drivers. Or:

Could you decrease the events/sec rate in the Wacom driver?
